Move to grid reference like warpd

[robrecord]

Some apps don't let their UI be detected by Homerow. In that instance, it would be nice to be able to move the pointer close.

Warpd has been able to do this by entering a grid mode where a couple of keyboard presses moves the pointer. Another of its modes splits the screen and allows the pointer to be moved into the split, into smaller areas getting consecutively closer to the target.

I use warpd but it's clunky next to Homerow and would love to see it use the same interface.i
